Geranium plant named ‘Duebapink’

ABSTRACT

A new and distinct cultivar of Ivy Geranium plant named ‘Duebapink’, characterized by its upright and outwardly spreading plant habit; freely basal branching habit; freely and early flowering habit; and red purple-colored single flowers with long pedicels.

BOTANICAL CLASSIFICATION/CULTIVAR DENOMINATION

Pelargonium peltatum cultivar ‘Duebapink’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ivy Geranium plant, botanically known as Pelargonium peltatum, and hereinafter referred to by the name ‘Duebapink’.

The new Ivy Geranium is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program was to develop new Ivy Geraniums with attractive flower and foliage colors.

The new Ivy Geranium is an induced mutation of a proprietary selection of Pelargonium peltatum identified as code number 95-13-01, not patented. The cultivar Duebapink was discovered and selected by the Inventor as a flowering plant within a population of irradiated plants of the parent selection in Rheinberg, Germany in June, 1997.

Asexual reproduction of the new cultivar by terminal vegetative cuttings taken at Rheinberg, Germany since July, 1997 has shown that the unique features of this new Ivy Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duebapink’. These characteristics in combination distinguish ‘Duebapink’ as a new cultivar and distinguish it from other known Ivy Geranium cultivars:

1. Upright and outwardly spreading plant habit.

2. Freely basal branching habit.

3. Freely and early flowering habit.

4. Red purple-colored single flowers with long pedicels.

Compared to plants of the parent, the selection 95-13-01, plants of the new Ivy Geranium differ in flower color.

The new Ivy Geranium can be compared to plants of the cultivar ‘Blizzard Pink’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Ivy Geranium differed from plants of the cultivar Blizzard Pink in the following characteristics:

1. Leaves of plants of the new Ivy Geranium had a zonation pattern whereas leaves of plants of the cultivar Blizzard Pink did not have a zonation pattern.

2. Plants of the new Ivy Geranium had longer peduncles than plants of the cultivar Blizzard Pink.

3. Plants of the new Ivy Geranium had longer pedicels than plants of the cultivar Blizzard Pink.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Flower and foliage colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Ivy Geranium. The photograph comprises a side perspective view of typical flowering plants of ‘Duebapink’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Duebapink has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment, such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photograph, following observations and measurements describe plants grown in Rheinberg, Germany during the summer under commercial practice in a glass-covered greenhouse with day and night temperatures about 18° C. and light levels about 4,500 foot-candles. Plants were grown with three plants per 10.5-cm container. Plants were about eight weeks from unrooted cuttings when the photographs and the detailed botanical description were taken.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 edition, except where general terms of ordinary dictionary significance are used.
